VEHICLE SUSPENSION SYSTEM
ABSTRACT OF THE DISCLOSURE
A pivot construction for a motor vehicle suspension system according to the present disclosure includes a pair of ball studs having shank portions fitted in the eye at the end of a leaf spring. The heads of the ball studs are each enclosed by a cup-shape polyethylene bearing that is retained within a socket. The sockets for the ball studs are supported by spaced portions of a bifurcated vehicle frame bracket. A pair of first seals retain lubricant within the bearings and a pair of second seals prevent the entry of contaminates into the spring eye that might corrode the surfaces of the shank portions of the ball studs.
Description
)8 The present invention relates to motor vehicle suspension systems and, more particularly, to a pivot construction for such systems.
In accordance with the present invention, there is provided a pivot means constructed to insersect first and second members for angular displacement of one of the members relative to the other of the members about a fixed pivot axis; the pivot means comprising a pair of ball studs; each of the ball studs having a shank porti~n and a head portion; the shank portions being in axial alignment with the ends of the shank portions being in juxtaposed relationship; a sleeve surrounding the shank portions supported by one of the members; a pair of socket means enclosing the head portions of the pair of ball studs; each of the socket means being secured to the other of the members; one of the socket means comprising a plastic bearing supported in a socket part; an annular retaining ring disposed in the socket part and engages the end of the bearing; the socket part having a peripheral lip engag-ing the retaining ring and exerting a preload on the bearing seat; a first annular seal having a portion engaging the peripheral lip of the socket part, the retaining ring and the shank portion of the most adjacent ball stud;
and an annular thrust washer and seal having a hat-shape metal core and an elastomeric coating over su~stantial portions of the exterior surface of the core; the thrust washer and seal sealingly engaging the shank portion of the most adjacent ball stud and the sleeve.
The pivot means of the invention is particularly useful in connecting the end of a leaf spring with a vehicle frame bracket in a motor vehicle suspension system.
~ 2 ~
The double ball and socket joint construction of this suspension pivot automatically compensates for minor misalignment that may occur between the leaf spring and the fxame bracket. Further, the ball and socket construc-tion offers minimum frictional resistance to angular displacement of the spring with respect to the frame bracket. In addition, the seal arrangement assures long bearing life and the pivot means is suitable for heavy duty truck application.
The present invention is described further, by way of illustration, with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of a motor vehicle suspension having a pivot construction embodying this invention;
Figure 2 is a sectional view taken along section line 2-2 of Figure l;
Figure 3 is an enlarged sectional view of a portion of the construction of Figure 2; and Figure 4 is a sectional view of the combination thrust washer and seal used in the suspension pivot of Figure 2.

3 The socket part 66 includes a radially extending 4 flange 69 that is constructed to receive a tool. This
12 The leaf s~ring 14 has its forward end formed with 13 a spring eye 16. A sleeve 19 is fitted within the spring 14 eye 16 and has its ends spaced from the ends of the eye.
The frame bracket 18 is provided with bifurcations 20 and 16 22 that are pivotally connected to the spring eye 16 by , 17 means of left and right ball and socket joint assel,~lies 24 r 18 and 26. These assemblies are of i ~ntical construction.
19 The left ball joint 24 includes a polyethylene bearing 28 of generally cup-shape construction which ; 21 encloses the ball portion 30 of a ball stud 32. The 22 plastic bearing 28 is retained within a socket part 34 23 by means of a retaining ring 36 and the spun-over edge 24 38 of the socket 34. The spun-o~er edge 38 exerts a load on the retaining ring 36 that preloads the bearing 28.
26 - The socket part 34 is situated within a hole 40 27 formed in the bracket bifurcation 20 and is located thercin 28 b~ a radial flange 42 tllat is seated agaillst tlle outside 1 face of~the ~ifurca~ion. The bifurcation 20 h~s a slot 44 2 that e~tends radially from the edge of the hole 40. T~e 3 socket part 34 is secured in the hole 40 by means of a 4 pinch bolt 46.
The ball stud 32 of the joint 24 has a shank 6 portion 4~ that extends into the interior of the sleeve 19.
7 An annular rubber seal 48 engages the end of the socket 34 8 and sealingly engages the retaining ring 36 and the shank 4 9 of the ball stud 32, .10 1 A combination thrust washer and seal member 50 11 has a generally hat-shape construction positioned at the 12 end of the spring eye 16. As seen in Figure 3, the men~er 50 13 is of composite construction with a metal backing piece that 14 supports a rubber piece.
